I've spent the last day and a half trying to take the copper colour off a piece I'm working on. I made fresh hot pickle, I left it in overnight, I left it in all day yesterday, I tried the hydrogen peroxide trick...nothing seemed to help. And I was quite baffled as to why only one component had gone pink when even the piece of silver soldered to it was fine.
Finally this morning I recalled that I had some notes about the failed experiment in wire knitting that I'd recycled to make the bit in question. Turns out it was actually silver-plated wire, not sterling.
I've succeeded in taking off the plating, all right - but it was silver plate from copper, not copper from silver!
Argh! How annoying... I wonder if I might have tried scraping the surface slightly; possibly not if I'd decided it was plating from the pickle.
*But* it's a really good demonstration of the benefit of a logbook.
A while back I popped into our local ironmonger and asked for a reel of copper wire. When I got home, the label said 'copper plated wire'. Copper plated what, exactly?

Peter, good point about the logbook - I should buy a proper book and start keeping everything together instead of scribbled on bits of paper (mind, I did know right where the bit of paper was, when I remembered its existence).
Dennis, the question is, what happens when you pickle the copper plated wire?!
I've remade the bits in question and, touch wood, I seem to have the whole thing soldered together. Will post pics when it's finished off.

Glad it ended well and very much look forward to some pix. My old teacher used to say 'It's the learning curve' and I would think, but not say 'b....r the learning curve, I just want to get on.' Dennis.
Pics on the show and tell board and in my album.
